Oh... I feel stupid now...

I don't really like either of them, I don't think I'm voting.

Jen had the most development of any Pink Ranger from the Post-Zordon seasons. Thus she wins.

But then, Pink Rangers don't seem get that much development anyway. Which sucks.

Alright,Jen won the Pink division! Now onto the Grack divi.....there's more pinks?....really? Oh.

Fixed. Kim, Kat, and Cassie don't have anything on Jen.

No contest, the Pink Rangers can just pack up right now because Jen wins this.

Had to vote for Cassie since it looks like no one else will. Cassie is the only Pink Ranger that I actually liked (though I don't know them all). Maybe I should watch some Time Force based on these votes.

There's gonna be one pink that makes us eat our words and go "oh,her!"

What about Kendrix and Karone?

You specified that Jen was best post-Zordon, which implied the pre-Zordon Pinks could even hold a candle to her (Spoiler alert: They can't).

Kendrix is the only one who I could conceivably see myself voting for aside from Jen.
I'm not sure on Karone. She didn't do much.
